 Ok. So that probably makes it a little on the large size for a personal belt carried hatchet. 
I have looked through the books that I have that include axes - Salaman, Kauffman and even Neumann - but have found no clue to explain the grooves on the spike. 
The secure fixing of the head with wedge and langets, which are too short to be defensive, suggests a hard working tool. 
Tool, fire axe, trench axe? I can only guess.
